Here is a doozy for you all! How shall I define sex (the verb) on this blog?
Honestly, I have never heard a good definition for sex. I think the definitions vary quite widely from person to person to be really useful. While I think that most people can agree that the penetration of a penis into a vagina to the point of one or more orgasms is sex, beyond that there seems to be serious questions. Is penetration without orgasm sex? Is anal penetration sex? Is fellatio sex, or cunnilingus, or penetration with a toy or oral sex on a toy or handjobs or...
I personally use a pretty broad definition of sex in my own life, but I feel that for a scientific blog it is crucial to use clearly defined terms.
So for the sake of this blog, I will make a serious effort to be clear about the kind of sex I am discussing here whenever possible. If I am unclear, please let me know so I can clarify. If the type of sex being discussed in a study or on some other source is not clarified, I will try to point this out (and will likely be generally annoyed by the lack of specificity).
